I had bought this as my first shorts to use in jiu jitsu no gi. I had purchased it as a size 30 since i am 5"4 about 140 lbs with a size 30 waist. I should've definitely read more reviews on it before purchasing but couldn't find any good ones. When i did find a review,it was too late. It had said it runs very tight by the waist and boy were they right. It ran very tight and i had to squeeze myself in. It feels like a 28 and it honestly doesn't fit me. I suggest anyone purchasing this item to GET A SIZE BIGGER than their original waist. It seems comfy and looks quite nice unfortunately, its the sizing thats the problem. Hope this helps anyone.
